Telco Customer Churn - Milestone 2 (EDA + Preprocessing)

Structure

data/            -> raw dataset (Telco-Customer-Churn.csv)
notebook/        -> telco_churn_eda_preprocessing.ipynb (full pipeline)
results/
  EDA_graphs/    -> 10 EDA plots (churn distribution, tenure, correlation, etc.)
  final_data/    -> X_train.csv, X_test.csv, y_train.csv, y_test.csv

Pipeline covered in the notebook

• Load + inspect data, fix TotalCharges dtype
• Missing value handling (median imputation)
• Duplicate removal, drop customerID
• Outlier check (IQR) on tenure / MonthlyCharges / TotalCharges
• 10 EDA visualizations
• Encoding: binary map, ordinal (Contract), one-hot (nominal categorical cols)
• Train/test split (80/20, stratified)
• Standardization (fit on train only, applied to test - avoids data leakage)
• Final datasets saved to results/final_data/
